When you hear Hillary Clinton and her apologists try to explain away what will surely amount to thousands of classified emails she sent and received during her tenure as secretary of state-make that tens of thousands- you need no more than listen to people who have experience over the years handling classified communications. How about former State Department security officials themselves?
Aside from intelligence agencies like the CIA and NSA, I can think of no government department or agency that sends more classified documents than the State Department. Her denials don't pass the smell test or the laugh test. She is a liar, pure and simple.
